To stop a volcano from destroying a local town you come up with a plan to drop a huge ice cube into the lava to cool it down so that it becomes solid rock. There is 40,000 kg of lava which has the following properties: Temperature = 1300° C %3D Melting point of lava = 1200° C %3D Specific heat of the lava = 840 J/Kg*C Latent heat of fusion for lava = 418 KJ/Kg How much ice at 0° C is needed to cool all the lava down into its solid form? Latent heat of fusion for water = 333 KJ/Kg Specific heat of water = 4186 J/Kg*C [Your answer will be in terms of Kg]
